Calculating the number of lines in a file?

Question

How would I calculate and display the number of lines and words that are contained in a .sh file?

Answer 1

Use the program wc.

• To count the number of lines: -l

    wc -l myfile.sh
  

• To count the number of words: -w

    wc -w myfile.sh
  

See man wc for more options.

Answer 2

As mentioned by souravc, you can use wc for this:

$ wc -w statusToFiles.sh 
10 statusToFiles.sh
$ wc -l statusToFiles.sh 
6 statusToFiles.sh

To only display the count itself, you can pipe that output to awk, like this:

$ wc -l statusToFiles.sh | awk '{ print $1 }'
6

...or as kos mentioned below:

$ < statusToFiles.sh wc -l
6

Answer 3

You can use grep command with blank matching string

grep "" -c file_path

Answer 4

You can also output the entire file with line numbers in front of every line using the command below:

cat -n myfile
